This widget displays the daily purchase rate in Yen for gold and Platinum. Just need to know that gold is 金 and platinum is プラチナ. Code is in middle of widget's web page, on bottom of central large window.

A great widget showing the exchange rates of the largest currencies to Yen, plus a Euro/US Dollar exchange rate. However, minimal Japanese is necessary, for example the names of the currencies in Japanese which is mostly in Katakana. If you want a translation of each currency, just send a comment to Bloglue!
